SPECIFICATION forming part of Letters Patent No. 551,186, dated December10, 1895.

` Appliaionrned January 30,1895. saai No. 536,730. (No man To ZZZ whomit may concern:

Be it known that I, SIMON GOLDNER, a citizen of the Kingdom of Roumania,residing in the city, county, and State of Newv York, have inventedcertain new and useful Improvements in lVindowCleaning Devices, of whichthe following is a specification.

rlhis invention has reference to an improved window-cleaning device bywhich both sashes of a window canbe readily cleaned from the outside ofthe window without necessitating the sitting on the sill and washing thesame from the outside, which mode of cleaning windows is connected withconsiderable danger of injury to life and limb; and the inventionconsists of certain details of construction, which will be fullydescribed hereinafter, and finally pointed out in the claims.

In the accompanying' drawings, Figure l represents a front elevation ofmy improved window-cleaning device, showing the same as applied to awindow-frame. Fig. 2 is a side elevation of the same, showing the sashesin vertical transverse section. Fig. 3 is a horizontal section on line 33, Fig. 2, drawn on a larger scale. Fig. 4 is a horizontal section online 4 4, Fig. 2. Fig. 5 is a vertical central section on line 5 5, Fig.4. Figs. 6 and 7 are details of the device for washing the glass panesof the sashes, and Fig. 8 is a vertical transverse section of the devicefor drying the same.

Similar letters of reference indicate corresponding parts.

Referring to the drawings, A A represent the sashes with which myimproved windowcleaning device is to be used.

The Window-cleaning device consists of a base portion B, which isprovided with a stationary piece l) near its inner end and with atransverse stationary piece b at its outer end. In the base-piece B isapplied the horizontal portion or shank of an angle-plate or slide C,which is preferably made of wrought-iron or other suitable material, andto which the lower end of an upright guide-post D is applied. To theunder side of the base-piece B is likewise applied a transverse stripb2, which rests against the bead on the sill A2 of the window-frame, asshown clearly in Figs. 1 and 2. An adjustable clamping-screw ZX isarranged on the inner stationary strip l), the

outer transverse piece b of the baseapiece B being placed against theouter surface of the lower rail of the sash or saslies A A', while theend of the clamping-screw is tightly screwed up against the innersurface of the lower rail of the sash or sashes A A', as shown in Figs.2 and 3. The upright post D is at'- tached by suitable screws orotherwise to the adjustable slide O, the guide-post being furtherprovided at its upper end with an arm D', which bears by means of anelastic strip or pad do against the upper part of the pane of the outeror inner sash, according as the outer or inner sash is to be cleaned.

The horizontal portion of the slide O is clamped in position on thebase-piece B by means of a clamping-screw O (shown in Figs. l, 2, and 3)after the slide is adjusted in the proper position in the base-piece B.On the upright post or guide-piece D is guided, by means of inner andouterantifriction rollers e and e0, respectively, avertically-reciprocating carriage E, which is preferably made ofsuitable sheet metal. As the carriage is of sleeve form, so as toencircle the post, and as the antifriction-rollers are arranged at thefront and rear of the same, there is absolutely no danger of thecarriage being accidentally displaced, and the saine is always guided onthe post without any binding action.

The upright post D is provided with a longitudinal groove CZ in itsouter surface for guiding the actuating-cord E, which is provided at itsinner ends with handles e', and which is guided by pulleys e2 e3,arranged near one side of the base-piece B, then over one half of adouble pulley e4, arranged in a recess in the lower part of the uprightguidepost D, then in upward direction through the carriage E and over aguide-pulley e5 at the upper end of the guide-post D, then along thegroove CZ of the guide-post, back over the second half of the doublepulley e4, and then over the guide-pulleys e3 and e2 at the oppositeside of the base-piece to the inside of the room. The cord E passesthrough a guidetube eX of the carriage E and can be iirmly clamped insaid guide-tube by means of a clamping-screw e, as shown in Fig. 5,'sothat the operating-cord E is firmly connected to the carriage and thelatter thereby compelled to follow the mot-ion of the cord E when thesalne is operated alternately in one or the opposite direction by thehands.

The carriage E is provided with pivoted and spring-actuated jaws ff (thespring being f) which extend from the carriage in forward directiontoward the glass pane of the sash, said jaws being preferably serratedat their adjacent edges, so as to engage the shank of a cleaning ordrying device F, according as the washing or drying of the glass pane isto be produced. The washing attachment is composed of a hollow tube F',provided with openings and open at one end for being supplied withwater. The shank and tube are surrounded by felt or other covering F2,as shown in Figs. G and 7.

The drying attachment is composed of a shanked tube F3 without aperturesand of a heavier felt covering F4, extending over the tube and shank, asshown in Fig. 8.

My improved cleaning device for windows is operated as follows: Thebase-piece B is placed in position on the window-sill, so that itstransverse strip lrests on the same, while the guide-post rests on theouter portion of the sill, the lower end of the guide-post being forthis purpose extended below the slide C. The outer transverse piece b isplaced against the lower rail of the upper sash after it is moved downinto the position shown in Fig. 2. The clamping-screw d is then appliedto the lower rail of the lower sash. The slide C is then adjusted in thebase-piece until the upper arm D' abuts against the upper rail of thesash, as shown in Fig. 2. The slide is then firmly clamped to thebase-piece. In this position the washing attachment is placed in thejaws ff of the carriage and is then in contact with the outer surface ofthe pane of the upper sash. The operating-cord E is then taken hold ofat its handles e and the same pulled alternately to such an extent thata vertically-reciprocating motion is imparted to the carriage of thecleaning device, the same being moved thereby from the upper to thelower rail and back again to the upper rail, and so on alternately.After the washing is completed the washing attachment F is removed fromthe jaws of the carriage and replaced by the drying attachment F3, whichis then moved in the same manner over the outside of the pane of thesash, so that the part just washed is thoroughly dried by the absorbentfelt covering of the drying attachment F3. The carriage is then movedlaterally suiiiciently so that the reciprocating washi ng attachment cantake the next adj oining portion of the pane of the sash, and then thisportion is washed and dried in the same manner as before. The washingattachment is then again moved along the sash and operated in the samemanner until the surface of the pane of the upper sash is cleaned. Theupper sash is then returned to its raised position and the slide C movedforward in the base-piece until the upper supportingarm D/ and thewashing attachment abut against the pane of the lower sash. The outertransverse strip l1 is then applied to the lower rail of the sash andthe clamping device to the opposite side of said rail, so that thewashing attachment is again in position for use, The operating-cord isthen again pulled alternately by the hands and thereby the carriage andwashing attachment moved alternately in upward and downward directionover the portion of the pane of the lower sash, this operation beingrepeated by moving the washing attachment gradually in transversedirection over the pane of the lower sash until the same is entirelycleaned. The device is then removed and put away, as the inner surfacesof the panes are cleaned in the usual manner from the inside of theroom.

The advantages of my improved windowcleaning device are, first, that ittakes up but little room and can loe quickly and readily applied tosashes for cleaning the same, the operation being performed entirelyfrom the inside of the room, so as to obviate any danger to life andlimb, which is incidental to the cleaning of windows when the person issitting on the window-sill; second, the windowcleaning device isoperated with great facility after the same is adjusted to the sash orsashes, as the up -and-down motion of the washing attachment does notrequire the exertion of great power, while the exchanging of the washingand drying attachments is readily accomplished when the carriage is atits lowermost position on the guide-post; third, the window-cleaningdevice, owing to its simple construction, is comparatively cheap, whileit can be stored away in any closet, as owing to its small width ittakes up comparatively little room.

Having thus described my invent-ion, I claim as new and desire to secureby Letters Patentl. In a window-cleaning device, the combination of abase-piece, a pair of transverse strips fixed to the upper part of thebase-piece and separated a suitable distance apart, a clamping-screwpassing through the inner transverse strip, a transverse strip fixed tothe under side of the base-piece, said strips and clamping-screw formingthe means for securing the base-piece in position, an upright postprovided at its lower end with a slide guided in the base-piece andprojecting below the slide at its lower end so as to rest on thewindow-sill, a carriage guided on the post, a washing attachment appliedto the carriage, and means for reciprocating the carriage, substantiallyas set forth.

2. In a window-cleaning device, the combination, with a base-pieceprovided with means for clamping the same to the lower rails of the sashor sashes, and to the window-sill, pulleys on the base-piece, an uprightguide-post supported on the window-sill and attached to the base-piece,a pulley j ournaled in the top of the guide-post, and a double pulleymounted in IOO IIO

guided at its midlength over the top pulley of the guide-post, While itsouter portions are guided respectively over the end-portions of thedouble pulley and the pulleys of the base- Io pieee, the ends of saidcord being provided with handles for reciprocating the carriage and theCleaning-attachment, substantially as set forth.

In testimony that I Claim the foregoing as my invention I have signed myname in pres- I 5 ence of tWo subscribing Witnesses.
